What Users Need from Inkscape PDF/PS Support

Color SVG's get turned black and white on export; needs to preserve colors

Better gradient supports. Xara Xtreme does a nice trick with gradients by creating colored steps aligned to the shape/direction of the gradient.

Better AI support. The Adobe Illustrator file format is a PDF-based format (after version 7), or postscript (before version 7). If Inkscape gains good PDF/PS support, it should also be able to load/save AI files.
